Comparison of Female Geriatric Lumbar-Extension Strength

Comparison of Female Geriatric Lumbar-Extension Strength: Asymptomatic Versus Chronic Low Back Pain Patients and Their Response to Active Rehabilitation

Bryon Holmes, Scott Leggett, Vert Mooney, Jean Nichols*, Scott Negri, and An Hoeyberghs

We compared lumbarextension strength between healthy asymptomatic geriatric females (HEAL) and symptomatic geriatric females (INJ) seeking medical attention for chronic low back pain. The INJ group used the MedX lumbarextension machine to perform isotonic exercise two times per week and were eventually reduced to one time per week, Range of motion (ROM) and strength were significantly different between groups before beginning the program. After the program, ROM and strength improved significantly and were not different from those of the HEAL group.

The average length of treatment was 97 days and 20 visits. Subjective pain ratings were significantly reduced (60%) and exercise weights significantly increased (71%). This reconfirms the notion that many back pain sufferers have weaker lumbarextension strength and that some symptomatic geriatric women can increase strength with progressive resistance exercise, which leads to decrease in low back pain.

The effects of exercise for isolated lumbar extensor muscles were examined in 54 chronic lowback pain patients. Subjects were randomly assigned to a 10week exercise program (N = 31) or a waitlist control group (N = 23). Results indicated a significant increase in isometric lumbar extension strength for the treatment group and a significant reduction in reported pain compared with the control group (P 0.05). Treated subjects reported less physical and psychosocial dysfunction whereas the control group increased in pain, and physical and psychosocial disfunction.

There were no concomitant changes in reported daily activity levels.These results show that lumbar extension exercise is beneficial for strengthening the lumbar extensors and results in decreased pain and improved perceptions of physical and psychosocial functioning in chronic back pain patients. However, these improvements were not related to changes in activities or psychological distress.

Key words: chronic lowback pain, lumbar extension strength, psychological distress

Effect of Workplace Based Strengthening of Low Back Injusry Rates

The Effect of Workplace Based Strengthening on Low Back Injury Rates: A Case Study in the Strip Mining Industry

The purpose of this study was to demonstrate the effect of a once a week exercise program focused specially at lumbar extensor strengthening. This is a comparative study where workers volunteered to exercise were compared to workers who did not exercise.
Low back claims for one year were noted to document efficacy of the training program. Change in strength was also noted. There was a 54% to 104% increase in strength during a 20 week program. The incidence of back injuries in the exercise group was .52 injuries per 200,000 employee hours versus the industry average of 1.09 back injuries per 20O,OOO employee hours.


The average incidence of injury for the previous nine years at the company participating in the program was 2.94 injuries per 200,000 employee hours. The injury incidence in the workers not exercising was 2.55 injuries for 200,000 employee hours.
The average workers’ compensation liability dropped from $14,430.00 per month to $380.00 per month for the study year. The significant increase in strength associated with the exercise program correlated with the greatly reduced incidence of back claims.

Concept 10 10 – Background

Concept 10 10 – Background

Concept 10 10 was developed and founded by Jorgen Albrechtsen, who is also the President of the international organization.


Founder - Jorgen Albrechtsen

In his younger years, Jorgen Albrechtsen had a great interest in karate. He opened his first school at the age of 17 and later studied in Japan and various countries in Europe. He eventually built and operated 20 karate schools and reached the rank of 5. dan black belt. The head school became the largest karate school in the world with 5,000 active members, which attracted worldwide attention. Jorgen Albrechtsen is also the author of 8 books on karate, exercise and nutrition.

Later on, he became interested in how to train the human body in the best possible way, realizing that the market was full of less than serious offers that constantly confused and frustrated consumers by their lack of results. He came in contact with Arthur Jones in 1980. Arthur Jones is the inventor of Nautilus and later MedX exercise equipment and the father of high intensity training and a scientific no nonsense approach.

Jorgen studied and trained with Arthur Jones and his associates, opened his first science-based high intensity training center in 1981 and expanded over the years with several more, including franchises.

During the last part of the 80´s, Jorgen became increasingly aware of the need for constant supervision and coaching if a member was to obtain good results, and he was also dissatisfied with the fitness trend that focused more on socialization, hype and glitter than on serious result producing exercise.

He then moved to Florida to further study and work with the various research results on effective training and with a wish to develop a system that would be the intelligent alternative and produce optimal results.
The result of his efforts and his more than 30 years of experience in the exercise field came to be Concept 10 10, which was developed and ready to launch by the end of 2003.
It combines the scientific research results with a focused environment where all disturbances have been eliminated and a personal trainer is involved from start till end of each workout. It also utilizes customized state of the art equipment.

The first center opened early 2004 and became an instant success. Jorgen Albrechtsen did not want to expand further for the first 2 years, as he wanted to first fine tune every part of the operation, evaluating the results from hundreds of clients etc.
In 2006, expansion was started, and Concept 10 10 is now a global operation with an ever increasing demand for more centers around the world.
